CMD Corp. (Booth S12028) claims its bag sealing and perforating technology can save converters about $100,000 per year per line.
The Appleton, Wis., firm says the exact placement of the perforation has been a challenge to converters producing bags at high speeds. The patented technology is being shown publicly for the first time at NPE2009.
Because our new technology creates a single seal with the perforation precisely centered, the problem of incorrect perforation placement, missing side seals, and excessive film in between bags is reduced, if not eliminated, said CMD President Steve Sakai. Bag lines running 600 feet per minute could save some 207,000 pounds of resin per year.
Greater reliability cuts film use and scrap and allows the bag-sealing line to run more efficiently, Sakai said at his firm's booth.
CMD equipment was running packs of tall kitchen bags at the booth using three-layer outsourced film. Two layers were ExxonMobil Enable metallocene resins; an inner layer of ExxonMobil's Exceed metallocene contained a white masterbatch. The resins allow downgauging with no loss in toughness and other physical properties, the firm said.
